These are bee stingers with the venom sacs still attached. I am not macho about beekeeping.I have no need to wear little or no protective clothing while working with bees, and I respect that the bees don't always want to be bothered. Especially when working a hive that I am unfamiliar with, as with this one.I picked these bee stingers off of my suit after trying to visit a hive on a friend's property.They did not want to be bothered. They let me know quickly.I learned my limits that night.I am content to work my own hives.
